PGA Tour: 3M Open Top 20

Platform comparison

Market context

The 3M Open is a four-day PGA Tour event at TPC Twin Cities in Blaine, Minnesota, running from 23 to 26 July 2026, with an $8.8 million purse and 500 FedExCup points on offer. In this market, a **YES** share pays out if the named player finishes inside the top 20 on the official PGA Tour leaderboard, including ties; a **NO** share pays out otherwise, so the key question is not just making the cut but holding position through Sunday’s final scoring. The market also has a hard backstop: if official results are not published by 1 August 2026 at 8:00pm ET, it resolves NO.[1][2]

An 81% crowd-implied probability suggests the market already prices a strong chance of a top-20 finish, which is typical when a player is viewed as well suited to the course, form, or field strength. That said, golf prediction markets can move quickly because one poor round, a missed cut, or a late-round slip can change the outcome dramatically. The 3M Open’s recent winning scores underline that TPC Twin Cities can produce low scoring, with past champions finishing at -23 and -17, so a player does not need to lead from start to finish to cash, but must avoid a volatile stretch over four rounds.[2]

The main catalysts are the start of play, live leaderboard swings, and any late field or tee-time changes before first round action. Tournament officials announced a 144-player field featuring 53 of the top 125 players in the Official World Golf Ranking, which gives some context for the competition level, but the official PGA Tour results remain the settlement source.[3][1] Traders should watch whether the player is in the field, whether they begin strongly enough to stay in contention, and whether weather or scoring conditions at TPC Twin Cities produce a compressed leaderboard where small mistakes push players in or out of the top 20.[1][4]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
